Wind Turbines Don’t Affect Property Values

I noted in my recent post on wind turbines and tourism that a related issue, wind farms and property values, was also important to consider. A new study does just that, and finds “no statistical evidence” of effects.

The “hedonic” in the study title refers not to hedonism in the colloquial sense (think college students living it up during spring break), but to the amount of pleasure — or displeasure — that comes from a certain amenity, like a nearby park, or disamenity, like a garbage dump.

In this case, the question is where wind farms sit on the amenity-disamenity spectrum.

What the Research Shows

Spatial Hedonic Analysis is not the first study to look at these issues. This work builds on reports of analyses by some of the same team members in recent years, and, as the study’s impressive literature review attests, work by others.

Still, this effort included analysis of an impressive and unprecedented level of data. It covered more than 51,000 sales of homes near wind turbines, in 27 counties in nine states — wherever they could get at least 250 relevant transactions. All of the homes were within 10 miles of wind farms (67 different facilities), and 1,200 of them were within a mile of a wind turbine.

And the upshot? Here:

Across all model specifications, we find no statistical evidence that home prices near wind turbines were affected in either the post-construction or post-announcement/preconstruction periods. (emphasis added)

Note that they can’t and don’t say definitively that there is no effect; absence of proof isn’t proof of absence. But, as the study puts it:

…if effects do exist, either the average impacts are relatively small (within the margin of error in the models) and/or sporadic (impacting only a small subset of homes).

Different states also have different characteristics, including demographics, population densities, and experience with energy development or natural resource use. But the research incorporated a wide variety, from Washington State to New York and New Jersey, and plenty of places in between.

What It All Means

No study is the last word, and these researchers may continue to find ways to increase understanding and “model fidelity.” But when we’re trying to make decisions about our energy future, it’s good to know what the best available research tells us about different facets of wind farms. Environmental costs and benefits, for example. Effects on electricity costs and rates. And, in this case, what it means for those who live closest, but aren’t benefiting directly from lease payments. (The research excluded “participating” landowners.)

Like tourists, neighbors will have different takes on wind turbines. But good, hard data on what a proposed wind project might mean when it comes to selling or buying in the neighborhood is a valuable contribution to the discussion.

Recently I was extremely low on cash and debts were eating me from all sides! That was UNTIL I decided to make money.. on the internet. I went to surveymoneymaker dot net, and started filling in surveys for cash, and surely I’ve been far more able to pay my bills!! I’m so glad, I did this.. – 36oz
